Golf club head

Abstract

A golf club head includes: a sole; a crown; a toe; a heel opposite the toe; a strike face generally bounded by a face perimeter edge, the strike face comprising a geometric center; a rear portion; and a substantially enclosed interior cavity at least partially delimited by the sole, the crown, the strike face, and the rear portion. The golf club head also includes at least one rib having a first portion secured to the strike face, having a second portion secured to the crown, and being positioned such that a location on the strike face laterally spaced toe-ward from the geometric center by no less than 0.4 in is associated with a COR value no less than 0.825.

What is claimed is: 
     
       1. A golf club head comprising:
 a sole; 
 a crown; 
 a toe; 
 a heel opposite the toe; 
 a strike face generally bounded by a face perimeter edge, the strike face comprising a geometric center associated with a first coefficient of restitution value and a strike face location spaced from the geometric center, the strike face location associated with a maximum coefficient of restitution that is no less than 0.825 and greater than the first coefficient of restitution value; 
 a rear portion; 
 a substantially enclosed interior cavity at least partially delimited by the sole, the crown, the strike face, and the rear portion; and 
 at least one rib having a first end and an opposing second end, the first end terminating at, and secured to, the strike face and the second end terminating at, and secured to, the crown. 
 
     
     
       2. The golf club head of  claim 1 , wherein the strike face location is toe-ward of the geometric center. 
     
     
       3. The golf club head of  claim 1 , wherein the at least one rib comprises a first rib and a second rib horizontally spaced from the first rib. 
     
     
       4. The golf club head of  claim 1 , wherein the first rib and the second rib are oriented generally perpendicular to the strike face. 
     
     
       5. The golf club head of  claim 1 , wherein the at least one first rib is oriented generally perpendicular to the strike face. 
     
     
       6. The golf club head of  claim 1 , further comprising a volume between 300 cc and 600 cc. 
     
     
       7. The golf club head of  claim 1 , wherein the maximum coefficient of restitution is greater than 0.83. 
     
     
       8. The golf club head of  claim 1 , further comprising a corrugation formed in the sole. 
     
     
       9. A golf club head comprising:
 a sole; 
 a crown; 
 a toe; 
 a heel opposite the toe; 
 a strike face generally bounded by a face perimeter edge, the strike face comprising a geometric center associated with a first coefficient of restitution value and a strike face location spaced from the geometric center a horizontal distance of at least 0.2 inch and associated with a second coefficient of restitution that is greater than the first coefficient of restitution; 
 a rear portion; 
 a substantially enclosed interior cavity at least partially delimited by the sole, the crown, the strike face, and the rear portion; and 
 at least one rib having a first end and an opposing second end, the first end terminating at, and secured to, the strike face and the second end terminating at, and secured to, the crown. 
 
     
     
       10. The golf club head of  claim 9 , wherein the strike face location is toe-ward of the geometric center. 
     
     
       11. The golf club head of  claim 9 , wherein the at least one rib comprises a first rib and a second rib horizontally spaced from the first rib. 
     
     
       12. The golf club head of  claim 9 , wherein the first rib and the second rib are oriented generally perpendicular to the strike face. 
     
     
       13. The golf club head of  claim 9 , wherein the at least one first rib is oriented generally perpendicular to the strike face. 
     
     
       14. The golf club head of  claim 9 , further comprising a volume between 300 cc and 600 cc. 
     
     
       15. The golf club head of  claim 9 , further comprising a maximum coefficient of restitution that is greater than 0.83. 
     
     
       16. The golf club head of  claim 9 , further comprising a corrugation formed in the sole.
